Features: 1ADVANCED TECHNOLOGY: The hydrogen water bottle utilizes Solid Poly Electrolysis (SPE) or Proton Exchange Membrane (for PEM) technology, which rapidly electrolyzes the water, separating and releasing the h2 and o2, enabling the production of hydrogen rich water. 2HIGH EFFICIENCY: The higher the mineral content of the water, the stronger the electrolysis effect and the higher the hydrogen content during the 3 minute micro electrolysis cycle of hydrogen production Be careful not to use non electrolyte water such as purified water, distilled water, etc., as there is no way to electrolyze the hydrogen molecules since the electrolyte in non electrolyte water is lower than 10. 3PROMOTES METABOLISM: Rich hydrogen water bottle will give you the best hydration to regenerate into your body and boost your metabolism in a nature way to improve sleep quality and skin health. 4STAINLESS STEEL BODY, LONG TEMPERATURE INSULATION: The hydrogen water bottle is made of upgraded stainless steel body, which is healthier and more hygienic; the doublelayer pumping body locks the temperature and keeps the water warm for 8 hours. 5HEALTH BENEFITS: Hydrogen enriched water is rich in hydrogen, which has potential antioxidant and health benefits, helps to improve muscle aches and pains, and reduces physical fatigue after working out. A perfect present for family and friends on birthdays, Halloween, Thanksgiving, Christmas, and anniversaries.
